Risk of accident
Clear all windows of ice or snow before set-
ting off. Impaired visibility could otherwise
endanger yourself and others.
i At very low temperatures, the rear win-
dow heating is only switched on once the
vehicle interior has warmed up.
i The rear window heating has a high cur-
rent draw. You should therefore switch it
off
as soon as the window is clear, as it only
switches itself off automatically after
between six and twenty minutes.
i If the battery voltage is too low, the rear
window heating may switch off.
X Make sure that the key is in position 2 in
the ignition lock.

tion mode
You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle
from outside. The air already inside the vehi-
cle will then be recirculated. G
Risk of accident
Only switch over to air-recirculation mode
briefly
at low outside temperatures. Other-
wise, the windows could mist up, thus
impairing visibility and endangering your-
self and others. This may prevent you from
observing the traffic conditions, thereby
causing an accident.
X To activate: press the , button.
The indicator lamp in the , button
comes on.
i Air-recirculation mode is activated auto-
matically at high outside temperatures.

ped
between the side window and the door
frame as the side windows are opened and

ing/tilting sunroof* manually after closing
using the convenience closing feature, it will remain in this position when opened
using the convenience opening feature. Switching the residual heat/auxiliary
ventilation on/off
It

is possible to make use of the residual heat
of the engine to continue heating the station-
ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the set interior temperature.
i The blower will run at a low speed regard-
less of the airflow setting.

The auxiliary heating/ventilation is auto-
matically deactivated after about 30
minutes, or when:
R the ignition is switched on
R the battery voltage drops Auxiliary heating/ventilation*
G
Risk of poisoning
Exhaust fumes are produced when the aux-
iliary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You
should therefore switch off the auxiliary
heating in confined spaces without an
extraction system, e.g. a garage. G
Risk of fire
When operating the auxiliary heating, parts
of the vehicle may become very hot, and
highly inflammable material such as fuels
could be ignited. Operating the auxiliary
heating is thus prohibited at filling stations
or when your vehicle is being refuelled. You
must therefore switch off the auxiliary heat-
ing at filling stations.
The auxiliary heating heats the air in the vehi-
cle interior to a temperature between 20 °C and 24 °C without using the heat of the run-
ning engine. The auxiliary heating is operated
using fuel directly from the vehicle's fuel tank.
For this reason, the tank content must be at
least at reserve fuel level to ensure that the
auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could automatically switch over
from ventilation mode to heating mode or
from heating mode to ventilation mode.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before activating
X
Set the temperature to a value between
20 † and 24 †.
The auxiliary heating/ventilation can be acti-
vated even when the air conditioning is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the desired temperature
within this range. If a higher temperature is
set, the vehicle is heated to 24 †. If a lower
temperature is set, the vehicle is heated to
20 †. Activating or deactivating the auxiliary
heating/ventilation The auxiliary heating/ventilation can be acti-
vated or deactivated via the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (
Y page 128).

X Slide the lower end of the mobile phone
into connector contact 2 in mobile phone
bracket 3.
X Push the top part of the mobile phone in
the direction of arrow 1 until it engages in
mobile phone bracket 3.
The mobile phone is connected to the
hands-free system and to the multi-func-
tion steering wheel.
The battery is charged depending on the
charge status and the position of the key in
the ignition lock. The charging process is
shown in the mobile phone display. i
The system reads the phone book stored
on the SIM card and in the mobile phone
memory. If the same entry is stored in both
of the phone books, both of these entries
will be shown in the multi-function display.
You can make a call using the s and
t buttons on the multi-function steering
wheel. You can control other mobile phone
functions via the on-board computer
(Y page 130).
i When you remove the key from the igni-
tion lock, the mobile phone remains
switched on for approximately ten minutes
(run-on time). If you make a call during this
time, the mobile phone will be switched off
approximately ten minutes after you have
ended the call.
Run-on time:
You can change the run-on time by making
an additional phone book entry on the SIM
card. For the name, enter "Idletime" and for
the number, enter a figure between "1" and
"30" (minutes). If you have not entered a
number or have entered a different num-
ber, the run-on time of ten minutes will still
apply. For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions.
Own number sending:
The hands-free system does not recognise
whether own number sending is enabled or
disabled in the mobile phone. The phone
number is therefore always sent by default.
By creating an additional phone book entry
on the SIM card, you can switch the own
number sending function on and off. For
the name, enter "CALLID" and for the num-
ber, enter a "0" or a "1". Entering "0" will
prevent the telephone number from being
sent; entering "1" will allow it to be sent.
For information on how to create a phone
book entry, refer to the mobile phone oper-
ating instructions.
